Summary of Naegleria fowleri (Primary amebic meningoencephalitis)
Naegleria fowleri is an amoeba that can be pathogenic, causing a fulminant brain infection known as primary amoebic meningoencephalitis. This microorganism is typically found in bodies of warm freshwater, such as ponds, lakes, rivers, and hot springs, and may gain access to the central nervous system through the cribriform plate. Amoebas can be seen on spinal fluid analysis. Amphotericin B, though not typically effective, is the treatment of choice.
